Least to greatest 2.3 2 4/5 2.6
Volgvan
2.3 is smaller than 2.6: we can see it just by looking at the digits from left to right.

now, where does 2\frac{4}{5} stand?

 its fraction part is equal to

\frac{4*2}{5*2}=  \frac{8}{10}

do that means that 2\frac{4}{5}=2.8

which is bigger than 2.6

so the final order is

2.3 2.6 2\frac{4}{5}

Is it linear or not? 2x+5xy-3=0.
ArbitrLikvidat [17]

The linear equation in slope intercept form: y = mx + b.

We have:

2x+5xy-3=0\qquad\text{subtract 2x from both sides}\\\\5xy-3=-2x\qquad\text{add 3 to both sides}\\\\5xy=-2x+3\qquad\text{divide both sides by}\ 5x\neq0\\\\y=\dfrac{-2x+3}{5x}

This is not a linear equation.
